RUNNING-GEAR.

SPECIFICATION forming part of Letters Patent N0. 770,727, datedSeptember 20, 1904. Application filed January 12, 1904. Serial No.188,684- (No model.) v

To all whom it may concern.-

Be it known that I, ALBERT F. MADDEN, a citizen of the United States,residing at Newark, county of Essex, and State of New Jersey, haveinvented certain new and useful Improvements in Running-Gears, of whichthe following is a specification, reference being had to the drawingsaccompanying and forming part of the same.

My invention relates to running-gears, particularly for self-propelledvehicles, though it will also be found of value for vehicles ofothertypes.

The object of the invention is to provide strong simple constructionwhich will permit free vertical movement of the wheels and body relativeto each other, but at the same time prevent, with as little friction andstrain on the parts as possible, relative movement or displacement inany other direction. For this purpose I employ, in connection with thebody of the vehicle, the axle, and the intermediate resilient devices, apedestal or guide at each end of the axle to prevent longitudinalmovement of the latter relative to the body and provide devicescooperating with the pedestal or guides to prevent lateral or transversemovement. I have devised a number of constructions for this purpose, oneof which is illustrated in the accompanying drawings, in Which- Figures1 and 2 are end and side elevations of the same, respectively.

The body of the vehicle is indicated by 1, preferably carrying abolster, as 2. Connected therewith in any suitable manner is a pedestal,which preferably consists of a pair of parallel guides or rails 3 4,arranged perpendicularly to the body. Only one pedestal is shown in thedrawings; but it should be understood that the same is duplicated at theother side of the vehicle. Extending through the guides or rails of thepedestals is an axle 5, having at each end an enlargement orrollersupport 6. In the present instance this enlargement or supportforms a part of the bracket carrying the steering-wheel 7 Revolu'blymounted on the bracket or enlargement and extending between the guidesor rails of the pedestal is a roller 8 above the axle having a flange 9.Below the axle is a roller 10, similarly mounted, also extending betweenthe guides 3 A. This latter roller, however, need not have an outerflange. Both rollers should be slightly smaller in diameter than thedistance between the guides or rails,

and the flange 9 on the upper roller should be wide enough to give afirm bearlng against the guides. The body is of course yieldinglysupported on the axle, as by means of leaf- 1 springs, one of which isshown at 11.

From the foregoing it will be seen that the axle and body .are free tomove vertically relative to each other and that during such movement therollers 8 10 will bear on one or the other of the guides or rails 3 4.The considerable distance between the rollers affords effectiveresistance against any tendency of the bracket to rotate, and at thesame time the flanges of the upper rollers prevent transversedisplacement of the axle relative to the body.

The construction herein exemplified accomplishes the objects of theinvention in a satisfactory manner; but this construction is typicalmerely and by no means the only form in which the invention may beembodied, and I therefore do not consider myself limited to that shown.

What 1 claim is 1. The combination with an axle, and avehicle-bodyyieldingly supported thereby, of pedestals carried by the body, eachhaving guides arranged on opposite sides of the axle, supports on theaxle adjacent the guides, and rollers carried by the supports, extendingbetween and bearing against the guides to prevent displacement of theaxle longitudinally of the vehicle, as set forth.

2. The combination with an axle and a vehicle-body yieldingly supportedthereby, pedestals carried by the body, constituting guides, supports onthe axle adjacent the guides, and rollers carried on opposite sides ofthe axle by the supports and bearing againstthe guides to preventdisplacement of the axle longitudinally of the vehicle, and means toprevent transverse displacement of the axle relative to the body, as setforth.

3. The combination with an axle having enlargements or supports at itsends, and a vehicle-body yieldingly supported by the axle, of pedestalscarried by the body between and adjacent to the enlargements or supportsat the ends of the axle, said pedestals constituting guides for theaxle, and rollers carried on opposite sides of the axle by the supportsand bearing against the guides to prevent displacement of the axlelongitudinally of the vehicle, as set forth.

4. The combination with an axle having enlargements or supports at itsends, and a vehicle-body yieldingly supported by the axle, of pedestalscarried by the body having guides or rails on opposite sides of theaxle, and rollers carried on opposite sides of the axle by the supportsand bearing against the guides to prevent displacement of the axlelongitudinally of the vehicle, as set forth.

5. The combination with an axlehaving en largements or supports at vitsends, and a vehicle-body yieldingly supported by the axle, of pedestalscarried by the body having guides or rails on opposite sides of theaxle, rollers carried on opposite sides of the axle by the supports, andbearing against the guides to prevent displacement ofthe axlelongitudinally of the vehicle, and means to prevent transversedisplacement of the axle relative to the body, as set forth.

largements or supports at its ends, and a ve-- hicle-body' yieldinglysupported by the axle,

of pedestals carried by the body having guides or rails on oppositesides of the axle, rollers carried by the supports and bearing againstthe guides, and flanges on the rollers cooperating with the guides toprevent transverse displacement of the axle relative to the body, as setforth.

7. The combination with an axle having steering-brackets at its ends,and a vehiclebody supported by the axle, of pedestals carried by thebody, constituting guides for the axle adjacent the brackets, androllers on the brackets above and below the axle, bearing on the guidesto prevent displacement of the axle longitudinally of: the vehicle, asset forth.

8. The combination With an axle having steering-brackets at its ends,and a vehiclebody supported by the axle, of pedestals carried by thebody, having guides or rails for the axle on opposite sides thereofadjacent the brackets, rollers carried by the brackets above and belowthe axle, bearing against the guides to prevent displacement of the axlelongitudinally of the vehicle, and means to prevent transversedisplacement of the axle relative to the body, as set forth.
